表面活性剂

胶束——表面活性剂分子的亲脂尾端聚于胶束内部,避免与极性的水分子接触;分子的极性亲水头端则露于外部,与极性的水分子发生作用,并对胶束内部的憎水基团产生保护作用。形成胶束的化合物一般为两亲分子,因此一般胶束除可溶于水等极性溶剂以外,还能以反胶束的形式溶于非极性溶剂中。
Capa superficial de un tensoactivo sobre una superficie de agua.
Micela.

表面活性剂(又称界面活性剂、乳化剂)是能使目标溶液表面张力显着下降的物质,可降低两种液体或液体-固体间的表面张力。表面活性剂一般为具有亲水与疏水基团的有机两性分子,可溶于有机溶液和水溶液。表面活性剂在溶液中的浓度超过某一临界值后,会自发缔合形成胶束(micelle)。胶束开始明显形成时的浓度称为临界胶束浓度(CMC),是表面活性剂的重要参数。
